S-PECIFICATION forming' part of Letters Patent No. 651,952; dated June 19, 1900- APPHCM'OII file February 16, 1900. Serial No. 5,470. (No model.)

, f'o all whom, it may concern:

Be it known that I, ABRAHAM PEARLSTINE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in a Combined Flask and Heater, of which the following is a specification.

My invention relates to anew and useful improvement in a combined fiask and heater, and has for its object to provide a fiask which ,can be used separate from the heating attachment, the same as those now in use, or can be readilyattached to the heating device and then can be set aside for a few minutes or placed in the ownerls pocket, and the colfee or other liquid V contained therein will be heated without any further attention from the user, thus enabling working people to heat their Coffee while they are working, and thereby having it in readiness to drink at mealtime, and this is especially advantageous to working people, such as motormen and couductors, working outside in cold weather, it often being necessary for them to occasionally have a hot drink during working hours, and as my device can be carried in the pocket while heating the beverage it is always ready for use.

Another object of my device is that' upon removing the fiask the heating attachment can be used for heating other articles of food.

With these ends in view the invention consists in the details of construction and combination of elements hereinafter set forth, and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to makeand use the same, the construction and operation will now be described inp detail, referring to the accompanying drawings, forming a part of this specification, in which- Figure 1 is a longitudinalsection of my improved device, showing the parts all assembled; Fig. 2, a side view of my device, showing the different parts removed from one another; and Fig. 3, ahorizontal section through the fiask.

In carrying out my invention as here emi bodied, A represents a fiask for holding the liquid to be heated.

B is a screw top covering the opening through which the fiask is filled.

O is the heatingcompartment, ,which is made in the same general Outline as the fiask A, and the fiask A is adapted to be inserted a short way within this compartment and rest upon the stops D, formed in the fiask A and `the compartlncnt O. An alcohol-lamp or other heating device E is inserted in the lower end of the heating-compartment C, thus furnishing means for heating the fiask A.

` It is obvious that for the properburning of the lamp E air should be supplied to the heating-compartment O. For this purpose I provide an air-duet F, which' extends from the'outside of the' top of the fiask downward through and a slight distance below the bottom of the same into `the heating-compartment C. At the opposite side of the fiask I provide a heat-flue G, which extends upward from the heatiug-chamber O through the fiaskto the outside of the top of the same. This heat-fine is for the purpose of carrying off the excess heat and` also for the purpose of radiatin git through lthe liquid. Elbows I-I H are provided, if necessary, at the top of the fiask and adapted to be inserted within the air-duet F and the heat-fine G and turned with their months pointing in the opposite direction from which the wind is blowing if the fiask is in an exposed position, thereby preventing the possibility of the lamp being blown out. w

To avoid the possibilty of theV lamp or heater E becoming overheated, I divide the reservoir I into two compartments by means of the horizont-al partition J. The upper compartment K is adapted to be filled with water or other coolin g liquid, a screw-cap and opening L being provided for filling this compartment. The lower compartment M contains the alcohol or other combustible fluid. A tube N extends from the outside of the reservoir into the said lower compartment M. This tube N is adapted to be removed lfor the purpose of filling the lower compartment M by unscrewing it from out of the fiange O, secured upon the top of the reservoir. tending through this tube is a wick P. A tubular piece Q extends upward from the partition J and has a water-tight connection with the top of the reservoir I, thereby pre- EX- Ioo venting .thercooling liquid from .fiowingin'to the lowerzcom parltment M. The t'ubeN .passes through this` tubular portion Q in passing to the lower compartrne'nt M. 'A cap R may be secured upon tli-e top of the tube N when the apparatus is not being used, thereby pre-. 'venting any evap'oration ofV the burnin'gfiu'id;

An opening S is provided in the heatingcompartment C, covered by suitable trans-3 parent materia'hfsuch as isinglass, T, for' the purpose of ohserving the burning of the lamp.

When itlis desired to heat other articles-of; food,the flask A is removed from the heating-compartment C and the articles to be heated are placed across the top of this heat? ling-comparttnent, thus furnishing a Satisfactory stove.` VOf course upon removing `the fla's-k A the air-duet` F is removed therewith, and .in using the 'heating-compartment C for heating other articles it would be necessary` For` this I provide a sliding Ventilator U, this' to furnish air 'thereto by other means.

venti'lator having therein a series of holes V,

which When slid inone direction are adapted 1 to .register with 'the series of holes X pro-.

Vided through the Wall of the heating-compartment CJ, A slot VV in the wall of the heating-compartment C, and the knob Y, se-

.cured to the sliding ventila'tor U and extendi'n'g through the slot, furnish means for the sliding of this ventilator.

When this apparatus is being used to heat 'the flask, the holesv V will be move-d out of v register with the holes X.

The advantages of my improvement are ob- Vious in that after the lamp is lighted it can be readily carried within the coat-pocket or put away in some convenient place until the liquid contained in the flask is heated., and,

if desired, the flask can be kept filled allday,

thereby insur-injg the own era hot `drink at any time, this being a great convenience to people required to work outside in cold weather. Having th'us fully descrihed my invention, what I claim-as new and useful is-- .1. In a combined flask vand heater, a. flask, a heating-compartment into which a portion 'of the fiask is adapted to be inserted, a heating ldevice adapte'dto he inserted within the heating-compartment, an air-duet extending from the outside of the flask downward throughV the same communicating with the heating-compartment, a heat-flue extending from the heating compartment upward through the flask to the outside of the same, removable revoluible elbows adapted to be inserted Within said air-duet and heat-flue, and i a sliding ventilator located within the sides of the heating-compartment, as specified.

2. In a combined flas'k and heater, a flask, aheating-compartment into which a portion of the flas'k is adapted to be inserted and rest upon stops suitably placed, an airL-duct ext'ending vertically'through the flas'k and communicating with the heating-compartment, a Verticalheat-fiue passing from theheatingcompartment through the' fiask, removable .revolubl'e elbows adapted to be inserted within the upper ends of the air-duet and heatflue, and a slidable ven'tilator located Within the sides of the heating-compartment, as and V for the purpose set forth.

In test-imony Whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.
